Structural Analysis Program for Civil Engineering.Can evaluate structures for static or dynamic seismic analysis. Dynamic analysis is made by accelerograms. Any analysis can be linear or non linear.

jif3d is a framework for joint inversion of different types of geophysical data in 3D. It currently comprises forward solvers for first arrival traveltimes, scalar and tensor gravity data, magnetics, magnetotellurics, electrical resistivity tomography and surface waves.The framework is flexible in terms of the coupling approach between the different datasets. At the moment cross-gradient coupling, variation of information and deterministic parameter relationships are implemented. Other...

CPSeis is the open-source version of ConocoPhillips' former seismic processing system. Uses Fortran 90 and C/C++ layers for I/O. The new system was designed using an MPI-parallel model and works well on Linux clusters or on individual workstations.

...Code and release files are primarily hosted on https://github.com/LabRPS/LabRPS and mirrored here LabRPS aims to be a tool for the numerical simulation of random phenomena such as stochastic wind velocity, seismic ground motion, sea surface ... etc. It can be in a wide range of uses around engineering, such as random vibration or vibration fatigue in mechanical engineering, buffeting analysis in bridge engineering....

Geophysical Library is a C++-library to handle geophysical data. At the moment the focus is on magnetotelluric and seismic data. It also includes a genetic algorithm for data inversion, signal processing and statistics routines.

JavaSeis.org: Java based software for processing and storing petroleum industry seismic data.

PRay stands for 'Plot Rayinvr' and is a graphical user interface for the ray-tracing software rayinvr (Zelt & Smith, 1992). In principle it can also be used as viewer for seismic traveltime data from other software like tomo2D. Zelt, C. A. and Smith, R. B., 1992, Seismic traveltime inversion for 2-D crustal velocity structure, Geophysical Journal International, 108(1), 16--34, 10.1111/j.1365-246X.1992.tb00836.x SYSTEM/USER REQUIREMENTS: - Linux/Mac OS X - You do need to be familiar with command line operations...

GSI student toolbox is a software package made for teaching purposes. It allows you to perform seismic inversion using global sthocastic inversion method made within CERENA/CMRP. NOTE: you can perform the same operations done with GSI Student Toolbox with our newest software GEOMS2. You can download the beta release here: https://sourceforge.net/projects/geoms2/

Given a set of seismic arrivals for one or more events, Bayesloc estimates the joint probability of event locations, corrections to travel time predictions, precision of arrival time measurements, and phase labels for the arrival times. Bayesloc also accepts probabilistic prior constraints on any of the input parameters, which can significantly tighten the distribution of all parameters.

RSTT is a software package that improves the accuracy of regional seismic travel time prediction and event location. The software package includes a computerized representation of 3-dimensional seismic wave speed for Earth's crust and shallow mantle (the outer-most 100 to 200 km of the Earth) and algorithms to calculate travel times for waves that are commonly used to locate events. RSTT was designed with real-time monitoring in mind and travel times can be computed on the fly in approximately 1 millisecond.

TotalDepth is an Open Source, cross platform, software collection that can process petrophysical data from the oil field such as wireline logs, seismic data and so on. Conventional, proprietary, software for petrophysical data tends to be expensive to licence, restrictive, slow to develop for and tied to expensive hardware. TotalDepth changes all of that. TotalDepth is open and cross-platform, and produces results straight to the bowser. TotalDepth supports such technologies such as HTML5, AJAX, Software as a Service (SaaS) and Cloud Computing.

Main Phase Modeling, MPM, is a implementation of a 2D staggered grid solution of the elastic waveequation, using a moving zone. This enables both efficient modeling of seismic wide angle data, and modeling of selected propagating phases.
